The one potentially interesting difference with ‘the gay community’(in addition to the usual factors by which everyone picks up their particular prejudices) is that they aren’t necessarily driven by sexual interest to interact with members of an out-group.
This is hardly to say that heterosexuals are induced to be nice by their tastes(indeed, as most frats-in-the-news stories suggest, sometimes its closer to a state of war than anything else); but they do have to do something if they want to get laid, establish a family/household/etc. Depending on the circumstances, this can involve overt exploitation and violence with a suitably grim justifying mythology; it can involve some vaguely benevolent application of strictly stereotyped gender roles; or it can involve attempts to associate on relatively equal terms; but it isn’t really optional(especially in cultures where homosocial interaction is prized; but requires regular proof that you aren’t being gay about your close homosocial interactions).
Homosexuals obviously aren’t going to be able to avoid running into people who make up ~50% of the population from time to time; but they do have the option of homosocial institutions that also encompass their members’ sexual activities. This doesn’t define what the outcome will be in terms of prejudice, beliefs on gender roles, etc. will be; but it is a pretty major difference in terms of how much more-or-less-non-optional interaction there is going to be; and your attitudes about the people you need to be able to deal with are often quite different from the ones it is more or less optional to deal with.
This doesn’t necessarily mean ‘better’ or ‘worse’; but it probably is a recipe for ‘different’ in terms of attitudes, beliefs, and behaviors between sexes.
(It’s hardly a direct analogy; but there are certain similarities in comparing race relations in the ‘deep south’ to various areas of the north and west: the south certainly worked to earn its dire reputation; but attempts to build a racial caste system also left it with a great deal of interracial interaction. The economic and demographic situation simply don’t allow for much else. Doesn’t mean it has to be amicable; but it isn’t really optional. In areas of the north and west, you don’t have the whole ‘explicitly hearkening back to the good old days of the caste system’ thing; but because absolute numbers are smaller, and many of them comparatively recent arrivals or descendants of those and in geographically segregated areas, it’s very possible to have little or no interaction; and as the really, really, ugly incidents that sprang up around school bussing and the like showed, strongly prefer it that way and drop all pretense of more-or-less benign neglect if circumstances try to change that.)
